An electronic circuit which provides an electrical incapacitation current to a living target. The circuit includes a high voltage power supply, a charge-storing capacitor connected by a high voltage lead to the high voltage power supply. The charge-storing capacitor stores a charge at high voltage as supplied by the high voltage power supply. The circuit further includes a switch, a step-up transformer including a primary coil a secondary coil, a resonant circuit and an output terminal serially connected through the secondary coil to the high voltage lead of the charge-storing capacitor. The primary coil is connected in parallel with the charge-storing capacitor through the switch. During the incapacitation, the output terminal is operatively attached to at least a part of the living target. When the switch is closed, the resonant circuit initially stores zero charge, and any gap if present between the output terminal and the living target undergoes electrical breakdown from energy stored in the charge-storing capacitor. After the electrical breakdown, the incapacitation current is provided substantially from the charge stored in the charge-storing capacitor. |
